You opened the app 10 times.

Not bug.. User skill issues...

It did that by itself when I started my PC

[blackholeearth]

you probably have 2 or More slider.exe in your computer. different places ... all has [v] run at startup checked..

to diagnose this::

1. install everything exe... (this can find any file on pc..)

   • https://www.voidtools.com/downloads/

2. open everthing exe.

   • enable Regex
     

3. search this win.*slider.exe$

   • if you see 2 or more slider like these . only Keep 1 slider.exe.. delete All the others..
     

[blackholeearth]

try new release 8.12

• it doesn't use litedb.
  • ldb doesn't allow simultaneous access to settings.db file. By default

BUT first.. use everyting.exe
and delete all of the Old brighness-slider.exe from computer

[blackholeearth]

dev note , correction:

Litedb woks in shared mode.. but NOT by default. !!! litedb-org/LiteDB#1453

Anyway , we fixed our problem..
